2. How you pay Income Tax
Pay As You Earn (PAYE)
Most people pay Income Tax through PAYE. This is the system your employer or pension provider uses to take Income Tax and National Insurance contributions before they pay your wages or pension. Your tax code tells your employer how much to deduct.
Self Assessment tax returns
If your financial affairs are more complex (for example you’re self-employed or have a high income) you may pay Income Tax and National Insurance through Self Assessment. You’ll need to fill in a tax return every year.
Income that’s not automatically taxed
Income Tax is no longer automatically taken from interest on savings and investments.
Tax on the State Pension and other benefits
Your tax code can take account of taxable state benefits, so if you owe tax on them (for example for the State Pension) it’s usually taken automatically from your other income.
If your only income is from state benefits, including the State Pension, HM Revenue and Customs (HMRC) will write to you if you owe Income Tax.
